Snapshot on Exchange 2010 server

-

hello,

i running exchange 2010 in virtual environment.

an associate of mine took shapshot of server using hyper v in february. no longer working us. safe delete snapshot , power down server though there 25gb left on hard disc?

ive seen merge chew lost of gbs in no time , merge never complete.

hi,

what’s os version of hyper-v host server?

what’s role exchange 2010 server?

in windows server 2008 or windows server 2008 r2 hyper-v, correct way delete un-needed snapshots is:

  1. delete snapshot
  2. power off vm
  3. wait patiently avhd merge vhd (depending on snapshot file size, might take long time)
  4. power on vm

note:

  • after merge complete avhd deleted system.
  • the vm must powered off merge of avhd vhd happen.
  • manually interrupting process can corrupt vhd - hyper-v has checks in place 'do no harm' if merge not successful , leave was.
  • the more constrained disk space system is, longer process takes.
  • there no way predict how long merge take.

windows server 2012 support live vhd merge, can directly delete un-needed snapshot, , vhd merge without vm shutdown.

while, above poster mentioned, export or backup vm before perform merge process if production server.

for more information please refer following ms articles:
